Monitoring Vaccines in Ultra Low Temperature Cryogenic Storage
Many of the latest generation of mRNA vaccines, including those for Ebola and Covid-19, need to be stored at temperatures as low as -70°C (-94°F). These ultra low temperatures pose a challenge for the Cold Chain. Dry ice can be used a refrigerant, and modern insulated containers can help maintain such cryogenic temperatures, but to ensure vaccine potency is retained temperatures must also be accurately monitored.
Many existing digital data loggers cannot measure below -50°C (-58°F). However, the EasyLog ULT range use highly accurate thermocouple probes that can measure as low as -100°C (-212°F), easily covering the deep frozen temperatures needed.
For fixed storage or in transit, EasyLog ULT data loggers help you maintain the vaccine cold chain at ultra low temperatures.

21CFR is a set of regulations issued by the US Food and Drug Administration (FDA). Part 11 provides the criteria for the FDA to accept electronic records as equivalent to signed paper records with regard to data security. Even outside the USA, 21CFR Part 11 compliance is fast becoming the de facto global standard for electronic records management and control in the pharmaceutical industry.
All loggers can be supplied pre-calibrated

White Paper - Temperature Monitoring Deep Frozen Vaccines
“I can’t emphasise enough the complexity of maintaining an absolute temperature from the depo to the distribution centre to the airplane to the delivery truck to the surgery and the refrigerator in the doctors.” - Nick Jackson, Head of Programmes and Innovative Technologies at the Coalition for Epidemic Preparedness Innovations
There is a trend emerging for vaccines that require storage at even lower temperatures. Since 2019 the first effective vaccines against Ebola have been approved for use, and these require storage at -60°C (-76°F). And some of the leading Covid-19 vaccines, including those from Pfizer and Moderna, need to be held as low as -80°C (-112°F).
These are mRNA vaccines, a new gene-based technology at the cutting edge of vaccine development. Traditional vaccines are made up of small or inactivated doses of the whole disease-causing organism, or the proteins that it produces, which are introduced into the body to provoke the immune system into mounting a response. In contrast, mRNA vaccines trick the body into producing some of the viral proteins itself. One important benefit is that the manufacturing process for mRNA vaccines is much faster, a vital consideration in the battle against Covid-19.
Maintaining the cold chain at these extremely low temperatures requires specialised packaging and handling procedures. It also presents challenges for monitoring the condition of vaccines.
Reducing Vaccine Wastage
Did you know that according to official figures, in the UK alone vaccine stock worth over £6.3 million was lost in 2018 due to poor storage conditions?
Vaccine potency degrades quickly, and can be completely lost in temperatures outside the storage range specified by the manufacturer.
EasyLog digital data loggers accurately measure the temperature of vaccines in storage and in transit so you can be sure you’re following best practice.
Calibration Assures Accuracy
All EasyLog vaccine data loggers are provided with a calibration certificate
They are calibrated using apparatus traceable to national or international standards
Each logger purposefully tested at the temperatures you will be using it in
